Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is made further
Describe in detail.Following example are used for illustrating this utility model, but it is new to be not limited to this practicality
The scope of type.
As depicted in figs. 1 and 2, the novel flat seam machine of one of the present utility model includes base 1 and machine
Shell 2, base 1 is rectangular, and base 1 bottom has cavity, and casing 2 is arranged on base 1 upper side
On, base 1 is provided with needle plate 3, needle plate 3 is positioned on the upper side of base 1 front end, needle plate 3
Sewing up in trajectory 9 and toward feedstock direction, there is elastic deformation；Feed spool 4 and feed lifting rock shaft 5
All it is rotatably connected on base 1, and is installed in base 1 internal cavities, feed spool 4 and lifting
Tooth axle 5 lays respectively at the both sides of needle plate 3, and one end of retainer is connected in the front end of feed spool 4, tooth
The other end of frame is connected in the front end of feed lifting rock shaft 5, and retainer is fixed with feed dog, wherein feeding
Axle 4 drives feed dog to move horizontally by retainer, and feed lifting rock shaft 5 drives feed dog to lift by retainer,
Motor 6 is connected in the rear end of casing 2, and the output shaft of motor 6 is paralleled with feed spool 4, certainly
Connecting in the front end of casing 2 and have depression bar, the lower end of this depression bar connects presser foot lifter, presser foot lifter position
In the top of needle plate 3, casing 2 is also equipped with servomotor, this servomotor and upper shaft phase
Connecting, for driving the lifting of depression bar, and motor 6 is motor, and motor 6 is positioned at servo electricity
The lower section of machine, the output shaft of motor 6 connects crank 62 in feeding, when the output shaft of motor 6 is past
Crank 62 reciprocally swinging in feeding can be driven, the reciprocally swinging of crank 62 in feeding when rotating again
Then drive feeding connecting rod 63 to realize swinging and the compound motion of movement, and then drive feeding lower crank
Reciprocally swinging, finally realize the reciprocating rotation of feed spool 4, and by controlling the rotation of motor 6
Angle then can control the pendulum angle of crank 62 in feeding, and then controls the rotation of feed spool 4
Angle, it is achieved the regulation to needle gage, therefore motor 6 be not only able to metering needle away from, additionally it is possible to band
The movement of dynamic feed dog, realizes feeding during rotating forward, realize backstitching, decrease power source during reversion,
Make overall structure compacter, feeding is only passed through between crank 62 and feeding lower crank feeding
Connecting rod 63 is in transmission connection, and not only saves the inner space of casing 2, and Stability Analysis of Structures,
